An action movie star researching a role is allowed to tag along with a hardboiled New York City policeman, who finds him superficial and irritating.

Nick Lang is a famous Hollywood actor, well known for his action movies. For his next movie, he needs the proper motivation and inspiration for his role, so he teams up with the reluctant New York policeman Lt. John Moss.

Not only must he endure Nick, who is laborious and out of touch with reality, but he must also catch a coldblooded murderer.
